Abstract: Distyryl compounds of the formula (I) ##STR1## wherein R.sup.1 denotes hydrogen, halogen, alkyl and the like,R.sup.2 denotes hydrogen, halogen, aryl, alkyl, aralkyl and the like,R.sup.3 denotes hydrogen, halogen, alkyl or CF.sub.3 andn denotes 1 or 2,are useful fluorescent brighteners which are distinguished by their low degree of self-coloring. They are particularly useful for application to polyester fibre materials by thermosoling.
